This category contains results about Inductive Sets.

Let $S$ be a set of sets.

Then $S$ is **inductive** if and only if:

\((1)\) | $:$ | $S$ contains the empty set: | \(\displaystyle \quad \O \in S \) | |||||

\((2)\) | $:$ | $S$ is closed under the successor mapping: | \(\displaystyle \forall x:\) | \(\displaystyle \paren {x \in S \implies x^+ \in S} \) | where $x^+$ is the successor of $x$ | |||

That is, where $x^+ = x \cup \set x$ |
